SPECIFICATION forming part of Letters Patent No. 441,566, dated November25, 1890.

Application iiled April 5, 1890. Serial N0. 346,661. (No model.)

To aZZ whom it may concern:

Be it known that I, JOSEPH HYLAND, of Charlevoix, in the county ofCharlevoix and State of Michigan, have invented a new and ImprovedCombination Tube and Pipe Cutter, Beader, and Expander, of which thetollowing is a full, clear, and exact description.

'lheobject of the invention is to provide a new and improvedcombination-tool for conro veniently and rapidly cutting pipes or tubes,expanding the same, and forming a bead thereon, as desired.

The invention consists of a tapering spin- `dle provided withlongitudinal dovetailed grooves, a cylinder held to slide on the saidspindle and provided with expanding-rollers, and cutting and beadingtools held to slide in the said cylinder and having dovetails fittinginto the said longitudinal grooves.

The invention also consists of certain parts and details andcombinations of the same, as will be hereinafter fully described, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the gures.

Fig. 4. is a transverse section of the same on theline y y of Fig. 3. Fig. 5 is a like view of the same on the line a z ofFig. 3. Fig. 6 is a similar view of the same on the line w w of Fig. 3.Fig. 7 is an end elevation of one of the outside knives. Fig. Srepresents detailed views of one of the inside knives. Fig. 9 is aperspective view of a dummy knife. Fig. 10 is a plan view, with parts insection, of the device for iurning and guiding the spindle. Fig. l1 is aperspective view of a spring-plate for the knives. and Fig. 12 is a faceview of the spindle-nut.

The combination tube and pipe cutter, beader, and expander A is providedwith a taperingspindle B, having on opposite sideslongitudinally-extending dovetails C and C', and also provided on itslarge end with a head B', adapted to be turned bya suitable tool ormeans hereinafter fully set forth.

The spindle B passes loosely through acylinder D, having on one end aslightly-n ished flange E and containing a series of expanding-rollersF, each of which is provided with an annular recess F and adapted totravel on 5 5 the outside of the spindle B. Each of the rollers F isprovided with trunnions F2, fitted to slide in radial grooves or slotsarranged 1n a cylinder D, so that the said rollers are moved outwardwhen moving the spindle Bthrough 6o the cylinder D from its small endtoward the large end. In order to conveniently hold the rollers Finposition on the cylinder D, the latter is provided with a head D',bolted or otherwise fastened on arms D2, forming guideways or recessesfor the reception of the rollers F. The latter are each provided with anannular recess, which is designed to form a shoulder on each side ofhead of boiler when expanding the boiler tube, the shoulders 7o forminga brace for the boiler.

In order that the rollers, while passing over the longitudinaldovetailed grooves C and C', may be held outward when the spindle ispassed through the cylinder D, as previously mentioned, dovetails G areiitted into the said dovetailed grooves under the said rollers, as isplainly shown in Figs. 3 and 6. Vhen the spindle is passed through thecylinder, all the rollers move simultaneously outward as the 8o spindleC increases in diameter.

In the head D' of the cylinder D are fitted to slide in suitable radialgrooves the inner cutters H, each of which is provided with a dovetailII', (see Fig. 8,) fitting into the cor- 85 responding dovetailedgrooves C or C', arranged in the spindle B. Thus When the latter ismoved through the cylinder D from its smaller end toward its larger endthe dovetails H travel in the said grooves and move 9o the cuttersoutward. At the same time that the spindle B is turned the cylinder Discarried with it, as the dovetails H engage the grooves C and C'. Thecutters H thus cut into the pipe or tube in which the device is used asthe spindle is moved farther through the cylinder D and is turned latthe same time. To assist in drawing the cutters back from the cut, aspring-plate H2 is placed on the inner end of the cutter above thedoveroo tail lI', the said the cylinder D.

In order to forni a bead on the end of'the tube or pipe, grooved rollersI are employed, mounted to turn on radial shafts having their bearingsin brackets J, each fitted to slide radially in a corresponding grooveE', formed on the inner face of the flange E, secured on the upper endof the cylinder D. Each of the brackets J is provided at its inside witha dovetail J', fitting into the corresponding dovetailed grooves C orC', so that when the device is used as a beader and the spindle B ispushed through the cylinder and turned at the same time the saidcylinder is turned with the spindle as the dovetails J engage thecorresponding dovetailed grooves C and C of the spindle B.

In order to cut a pipe or tube preparatory to bending where it projectstoo far beyond the outer side or face of the boiler or fine plateresting on the inside of head, the brackets J, carrying the beading--rollers I, are removed and cutters K are in serted in the correspondingslots formed in the cylinder D, each cutter being circular and mountedto turn in a frame K', having a dovetail K2, adapted to engage thecorrespondingly-shaped dovetailed grooves C or C' in the spindle B.

In order to conveniently remove or insert the cutters II aud K and thebeader-rollers I, with their brackets J each dovetail groove C or C isprovided at the small end of the spindle B with an enlargement C2, and asimilar enlargement C is formed at the large end of the spindle Bin thesaid groove. Now, when the operator desires to change the beadingrollersI for the cutters K the cylinder D is moved onto the large end of thespindle B, so that the dovetails J of the brackets J pass into theenlarged recesses C3, thereby permitting ot removing the brackets J fromthe head D and inserting the bracket K and cutters K in place, so thatthe dovetails K2 pass into the recesses C3, and when the head D' is nowslid toward the small end of the spindle the said dovetails K2 engagethe correspondinglyshaped grooves C and C'. In asimilar manner thebracket K' and critters K can be eX- changed again for the brackets Jwith the rollers I, as described.

For removing the inside cutters Il the cylinder D is moved to the smallend of the spindle B until the dovetails Ii' of the said cutters engagethe recesses C2 in the grooves C and C', so that the said cutters can betaken out and dummy cutters K3 can be substituted, so as to iill up t-heopenings in the head D previously occupied by the cutters II.

In order to conveniently turn the spindle B and to gage the same, thefollowing device is provided: In the head B' of the spindle B are formedtransverse openings, one of which can be engaged at a time by a pin L,held in a U -shaped arm N, in the middle part of which is mounted toturn one end of a screw-rod O, screwing in a U-shaped frame I andprovided at its outer end with a liead adapted to be turned by means ofa wrench or other suitable tool. In the legs oi' the U-shaped frame I)are fitted to slide the rods Q, extending in line with the axis ot' thespindle B and adapted to be fastened in any desired position by thesetfscrews R.

Then the device is used for cutting at a certain distance on the insideof the pipe or tube, then the rods lQ are adjusted in the legs of theframe P until the cutting-tools are in the proper position, after whichthe rods Q are fastened in place by the set-screws R, the inner ends ofthe s'aid rods resting against the boiler-plate. rlhe opera-tor thenturns the head O', and the screw O screws in the said frame P and pushesin the spindle B, so that the cuttingtools or the rollers are caused toslide outward to cut or expand the tube. It will of course be understoodthat before the screw can exert this pushing action the inner cutters IIor the dummies K3, as the case may be, must be thrown outward into firmengage ment with the interior of the tube, and then when the screw isturned inthe proper direction its tendency will be to draw the framePtoward the boiler-head. This device is also designed to draw back thespindle, so as to let the knives down from the cut in case they getstuck therein, so as to not break oit' the end of cutting-tools.

It is understood that when the device is used only for cutting a tube onthe inside the cutting-tools H are inserted in the head D'of thecylinder D and the spindle B is turned and at the same timepushedinward,so as to feed the cutting-tools against the inside of thepipe until the latter is cut. When the pipe is to be cut near its outerend, then the cuttingtools K are inserted in place of the brackets J,and the above-described operation is, repeated-that is, the spindle B isturnedand pushed inward to feed the circular cutters outward. When theouter end has been cut oii, the cutters K are removed, andthe bracketsJ, with the beading-rollers I, are inserted inside, and then the spindleB is again turned and pushed inward, so as to force the rollers I, withtheir grooves, in contact with the cut edge of the pipe or tube, so asto form a bead thereon.

In order to prevent the head D from sliding off the spindle B, thelatter is provided at its smaller end with a reduced screw-thread B2, onwhich screws a nut S' against the collar S, abutting against the smallend of the spindle B, as is plainly shown in Fig. I. This serves toprevent the cutting-tools and dummy knives from being displaced from thespindle when the latter is pulled forward in the tube. The nut andwasher ma-y be formed in one piece, and on the washer are pivoted thedrop stops or closures S2, adapted to fold over the slots of the spindleand to cover the said slots to keep the cutters in proper place. Inorder to remove the cutters, the stops or closures are opened.
